Navigation on this expedition should be pretty straightforward; right now (April 06) I'm fine-tuing my route and entering navigation data into my GPS, as well as in paper logs (in case the GPS fails) which will eventually be laminated as 'last-ditch' survival cards I'll dsitribute here and there in my gear (s that, for example, if I lose my sled in a crack in the ice, I could still have a nav card in my pack, or vice-versa). My charts and nav log will tell me what directions to go, daily, or hourly, and to stay on track, I use the compass you see above. This is a ship's compass (manufactured by Nexus of Sweden), about the size of an apple, that I've sewn into a neck harness (no metal, so it won't be thorwn off by magnetic fields) that hangs the compass securely between my belly and upper chest. So, above, you're looking straight down at my chest, and seeing what I've spent hours staring at: the compass bearing (right now on 105 degrees East). To avoid having to stop every once in a while and pull out a hand compass, I prefer to keep moving, an just glance at my ship's compass on occasion. The compass sphere contains oil, which won't freeze, and allows the compass card to swing slowly and steadily as the housing moves around it, just like the '8-ball' (horizon indicator) does in an airplane. This is a beautifully stable compass, and once it 'grabs' magnetic North, it doesn't let it go, no matter how much I might lurch or zig-zag through the snow. The following video clip shows the compass card remaining stable as the housing moves around it: CLIP.
